Article Overview
This article explains how to review cardiology documentation to determine whether a diagnostic catheterization was already performed or whether the encounter supports only the intervention. It is aimed at coders and billing staff who work with cardiac procedures and need to interpret procedure notes, access-site documentation, and supporting pre-procedure history to understand whether a separate diagnostic service is relevant. The discussion focuses on general documentation cues, timing of prior studies, and the role of the history and physical in clarifying the record.
Why This Topic Matters
Correctly identifying whether a diagnostic cath is separately billable affects how cardiac intervention encounters are reported and helps avoid duplicate billing. The article matters to anyone coding cath lab services because the distinction depends on documentation context rather than the intervention alone.
